Weight reduction is a great thing; I just don't think GM will hit their goal in such a short time period. If they do that's great; but no doubt it will drive up the cost of vehicles. I also wonder how they can reduce so much weight without compromising safety. Let's hope they can do it all; a lightweight, high-performance car that gets great gas mileage with a 5-star safety rating.

CAFE standards were not created to reduce pollution. Remember that when debating this stuff folks.

Weight reduction is a great way to increase performance and efficiency if they do it right. Removing weight in the right places can lower the center of gravity and removing weight in general will help in nearly all aspects of performance. I doubt they'll be able to cut fleet weights by 15% by then, but it's not like it is the end of the world if they don't quite meet the stated goal.

It's not weight reduction that is a bad thing per se. It's a good thing. To summarize my last post, they are saving weight by doing things that cost a lot of money instead of finding ways to get rid of useless features that add weight and cost but are being FORCED onto the cars.

This is a positive sign that the "thinking" is going in the right direction, and that GM wants to do business in a profitable way. This type of thinking (among other aspects) is what will get future buyers.

Its easy to say, go cut 400lbs off... actually doing it is going to be a challenge, and one thats not insurmountable.

For example, go pick up a rear view mirror from a 70's/80's car, and then pick up one from a 2005+ model... theres a huge weight increase... in 1 part thats not even structural.

GM just needs to trim weight on everything, not removal of mass but actual engineering to do the same job with less/lighter materials.

The same is true for the "Shut up, because it's gonna be AWESOME!" but in 12 months the "Hey!!!! THIS SUCKS! What idiot said they should do this?!?!?!" crowd.

...now that statement sounds like something coming from the oval office that we have been putting up with for how many years now, and it's the most most recent gaff that the press secretary is trying to spin.....a play on words, not to you Captain <place that post in context to the current events>...ooops, no politics...sorry....

CAFE standards were not created to reduce pollution. Remember that when debating this stuff folks.

Please DO NOT keep this in mind because it is actually incorrect.

CAFE was enacted after the 1975 Oil Embargo as a way to force people to reduce consumption of imported oil.

In 1975, the US imported about 15 Million barrels per day. CAFE was put into effect and completely failed in the stated objective. imports were up to about 18 million per day by 1978.

Consumption took a reduction back down to about 14 billion barrels a day by 1980 when the "Malaise" recession took hold. Over the next few years, the economy was booming again and consumption returned to the former levels and then continued to rise.

By 2025 the consumption rate is predicted to be 30 billion barrels per day (twice that of the consumption in the day when CAFE was imposed to reduce consumption).

So, CAFE has failed at the stated purpose, and while cars have gotten more efficient and use less gas, it still has not done anything to reduce dependency on foreign oil. It has done the opposite, by making people drive MORE now because it costs less to do so.

It has also resulted in compromised vehicle designs that need to make up for their inherent lack of safety with the addition of expensive pyrotechnic safety devices and the like, adding to the sticker price of the average car.

Backup camera as is way more useful and a lot lighter than a spare tire & jack. Neither one of them have to be used and if I had to have one it would be the lighter of the two.

I may not have to use it (and never will, as I'm capable of driving all by my self), but I'll still have to pay for it. How does that make sense?

I know how light those mirrors are. I picked one up just last summer after it fell off.

You've hit on a defining characteristic of the regulatory state. And in the case of our specific one, what we get is generally more in line with what we deserve.

Those numbers sound more like total oil consumption, not imports. I'd have to do more research on exact numbers, but I think that around the late 70s, roughly 30% or so of the total use was from imports. 30 years later, it was more like 70% of the total was imports.

Today, the percent of use that is imported is rapidly going down, largely due to shale production, with a significant and growing percentage of the imports coming from Tar Sands from our friendly neighbor to the north. (Which is the reason WTI oil is around $20 a barrel cheaper than Brent). And the government and EPA are fighting both of these new sources of oil as hard as they can....which would suggest that despite claims that reducing imports is the purpose of CAFE, the actual motives are different.

Interesting addition to the point about CAFE driving the SUV craze. I've always held that opinion as well....And it makes you to wonder what affect it would have had on fuel consumption of people had still been able to find full size sedans that got low to mid 20s on the highway instead of SUVs that got upper teens at best.

It really got rolling with Ralph Nader's crusade against GM, which just happened to coincide with his quiet buying up of Ford stock. I'm sure the two were unrelated, though.

No. CAFE was passed by Congress in 1975 after the 1973 embargo by OAPEC, Tunisia, Egypt and Syria. The embargo was an oil starvation tactic by the aforementioned countries in response to the United States' military-industrial support of Israel during the Yom Kippur War. In fact, numerous European (and Asian) countries denounced the actions of the United States because they did not want to suffer the economic backlash from the major oil producers in the region. CAFE was and still is intended to reduce the growth rate of oil demand to dampen the US economy from crashes based on natural or unnatural fluctuations in oil supply. The intention was to remove as much external petroleum-based manipulation of the US economy as possible. I'll revisit the emphasis on growth rate a little later.

Neither of those figures are evenly remotely accurate. Those are total consumption figures and as variables exogenous to relavent consumption models, like population growth and increase in demand for automobiles, saw record growth in the short-term preceding those figures they are meaningless without comparing their growth relative to said variables. You also don't seem to know something extremely important -- CAFE standards, though enacted by Congress in 1975, did not take effect until 1978

First of all, again your numbers are way wrong. Global oil consumption is only projected to be in the 120 million bbl/day range by 2025. Not a small figure, but your numbers are literally impossible. Are you suggesting that US oil consumption would be lower had CAFE never been introduced? CAFE was intended to minimize the growth rate of oil demand effectively reducing market volatility, nobody expected it to actually stop or reverse growth, and based on any reasonable models it has contributed greatly to that goal.

Let me break down the numbers for you very clearly. Below are the figures for annual US oil consumption in million bbl/day from 1960-2010. These are figures from my firm's database so I can't link you to them directly, but feel free to check any of the consumption figures; they are accurate. I calculated the annual increase with a simple calculation in R, but again feel free to check them for yourself.

So, even including the external decrease in supply and resultant demand shift from the OAPEC embargo in '73-'75, the average annual growth rate of oil consumption from 1960-1978 before CAFE regulations began was 3.774%. That was the AVERAGE growth rate of consumption year-over-year. After CAFE regulations began in 1978, average growth rate of consumption has been 0.124%. Average growth of consumption after CAFE regulations has been less than 1/30th of the average growth rate before CAFE.

Since CAFE regulations began we have not seen one single year that has topped the AVERAGE growth rate of consumption before CAFE. Even if we used only the statistical outliers, the highest single annual growth rates since the first CAFE standards took effect, we would still be significantly lower than the average before CAFE standards. Population has grown, # of vehicles has grown, miles driven has increased massively, but consumption of oil is damn near equal to what it was the year CAFE first came into effect. That is success, my friend. So please tell me again how CAFE hasn't worked at all.

Well, by 2025 I believe the country will have released itself heavily from foreign oil by using its cleaner burning natural gas. Trucking fleets are moving towards LNG and its only a matter of time before vehicles move towards it as well. You don't lose any power from gas to LNG, burns cleaner, it's cheaper and we have so much of it we can't store it any longer.

Ehhh, it's actually 100% factual. I hope you read my whole post because you just might learn something if you pay attention...

I read a good deal of it...learned some stuff. Thanks!

I agree with you, although I thought Natural gas didnt' contain the same amount of energy as gasoline, so more of it is needed to get the same power...thus less fuel economy. No matter...it will become more the norm over the years, especially as you say, for fleet trucks.

which trucking fleets?? I work for one and have heard no such thing, I hope they'd tell me since I repair the tractors lol

kinda like e85? it's cheaper but requires more to burn to get the same mileage

Well I haven't researched them but FedEx being one. I know we're getting off topic here so research CLNE and you'll see their investment in NG highway fueling stations built and 2013 stations plan. GE is developing at home fueling stations for LNG as well. It's on the way, now I'm not sure about it working well in high performance.

As for same energy, one trucker mentioned conversion to LNG from gas and said he's lost no power and pays around $1.40 a gallon. Caterpillar is working on development of NG engines and I believe Westport?

I half-wanted to remove all the political posts in here, but because there are so many - I'd be more justified in deleting the thread outright....however, I can't (and don't want to) do that. So - no infractions will be issued, either.

However - from this post on, all politically-fired posts will be removed, regardless of what was said above this post. It's only a few people who are instigating this...you know who you are: please stop. Let this thread right itself on the "GM CEO wants cars to get 15% lighter in 3 years" track.
